Diffie-Hellman cipher suites

Hello,

We use SoapUI 5.0.0
Build Date: 20140409-1012, Java version 1.7.0_40

When we configure Diffie-Hellman cipher suites at our apache server
TLS_DHE_RSA_WITH_AES_128_CBC_SHA, openssl: DHE-RSA-AES128-SHA
TLS_DHE_RSA_WITH_AES_256_CBC_SHA, openssl: DHE-RSA-AES256-SHA

we get the following error with soapui:
javax.net.ssl.SSLException: java.lang.RuntimeException: Could not generate DH keypair
caused by
Caused by: java.security.InvalidAlgorithmParameterException: Prime size must be multiple of 64,
and can only range from 512 to 1024 (inclusive)

This is a known problem:
https://httpd.apache.org/docs/trunk/ssl ... tml#javadh
but we our security requirement is to use 2048 bit primes sizes or higher.

Another webservice client program running under java 1.7.0_72 has no problem with it.

We tried several things with soapui which didn't work:

a) newest version of bouncycastle bcprov-jdk15on-151.jar : no effect

b) newer java version (1.7.0_72) :
handshake problem during CLIENT_HELLO already

Any help is really appreciated!

Are there any plans from smartbear to use a newer java version?

Regards,

Nils
